Description

Collagen CAS NO 9007-34-5 is a naturally occurring, fibrous structural protein that serves as a primary building block for connective tissues in animals. Its unique triple-helix structure provides exceptional tensile strength and biocompatibility, making it a versatile and indispensable biomaterial across numerous industries. This high-purity product is essential for manufacturers in the pharmaceutical, nutraceutical, cosmetic, and biomedical engineering sectors seeking reliable, quality-assured raw materials.

Application

• Pharmaceutical & Medical Devices: Used as a key excipient in capsule shells (hard and soft gelatin), as a matrix for drug delivery systems, and in the manufacture of wound dressings, hemostats, and surgical sponges.
• Nutraceuticals & Dietary Supplements: Incorporated into powders, capsules, and gummies for joint health, skin elasticity, and overall wellness support due to its bioavailability of amino acids like glycine, proline, and hydroxyproline.
• Cosmetics & Personal Care: Valued as a film-forming humectant and moisturizer in anti-aging creams, serums, lotions, and hair care products to improve skin hydration and texture.
• Tissue Engineering & Regenerative Medicine: Serves as a scaffold material for 3D bioprinting, cartilage repair, and bone graft substitutes due to its excellent biocompatibility and ability to support cell growth.
• Food & Beverage: Employed as a functional protein ingredient for texture modification, gelation, and stabilization in products like yogurts, desserts, and protein-fortified beverages.
• Research & Development: Used as a standard or substrate in biochemical and cell culture studies related to extracellular matrix biology, tissue repair, and material science.

Quality Control

Our collagen is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and functionality, referencing standards such as USP-NF, EP, and FCC where applicable. We provide comprehensive Certificates of Analysis (COA) with key parameters including protein content, viscosity, bloom strength (for gelatin), microbiological limits, and heavy metal content to guarantee suitability for your intended application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
